[texts]Osteology of Simosaurus gaillardoti and the relationships of stem-group Sauropterygia (Volume Fieldiana, Geology, new series, no. 28) - Rieppel, Olivier
Simosaurus gaillardoti H.v. Meyer, 1842, is recognized as the only species of its genus. An amended diagnosis of the genus is given here. Simosaurus mougeoti H.v. Meyer, 1842, is a lower jaw of Nothosaurus; Simosaurus guilielmi H.v. Meyer, 1847-1855, is a junior synonym of Simosaurus gaillardoti. The skeletal morphology of Simosaurus is redescribed in detail and compared to that of other stem-group (non plesio- and pliosaur) Sauropterygia (including Placodus)...

[texts]New interatheriines (Interatheriidae, notoungulata) from the Paleogene of central Chile and southern Argentina (Volume Fieldiana, Geology, new series, no. 42) - Hitz, Ralph B., 1964
Two new interatheriines (Interatheriidae, Notoungulata), Santiagorothia chiliensis and Proargyrohyrax curanderensis, are described from the transitional Eocene/Oligocene Tinguiririca Fauna, central Chile, and from roughly coeval localities in Chubut and Rio Negro provinces, Argentina. The former occurs in both central Chile and Argentina, whereas the latter occurs only in Argentina. Several Argentine specimens are referred to Eopachyruchos, an interatheriine for which an emended diagnosis is pre...

[texts]The intramandibular joint in squamates, and the phylogenetic relationships of the fossil snake Pachyrhachis problematicus Haas (Volume Fieldiana, Geology, new series, no. 43) - Rieppel, Olivier
A review of the morphology of the lower jaw in varanoid squamates, including mosasaurs, and basal snakes (scolecophidians, anilioids, basal macrostomatans) reveals a greater degree of variability in the differentiation of the intramandibular joint than had previously been recorded. In particular, the mandibular joint of mosasauroid squamates and snakes differs fundamentally. In mosasaurs, the dentary is primarily suspended from the prearticular and the posteriorly concave splenial receives the a...

[texts]Revision of the Sauropterygian reptile genus Cymatosaurus v. Fritsch, 1894, and the relationships of Germanosaurus Nopcsa, 1928, from the Middle Triassic of Europe (Volume Fieldiana, Geology, new series, no. 36) - Rieppel, Olivier
Three species are currently recognized within the genus Cymatosaurus from the late Scythian and early Anisian of Europe, viz. Cymatosaurus fridericianus v. Fritsch, 1894, Cymatosaurus latifrons Guerich, 1884, and Cymatosaurus multidentatus (F.v. Huene, 1958). All other previously described species of Cymatosaurus are considered either junior synonyms of Cymatosaurus latifrons (C. gracilis Schrammen, 1899; C...
